Adjusting Knob Light Grey 003750204

The Lindhaus Adjusting Knob in light grey (part# 003750204) is a genuine Lindhaus replacement part shared across several Lindhaus power-nozzle machines. The Lindhaus Adjusting Knob is the control the operator turns to set the nozzle’s carpet-height adjustment, raising or lowering the brush so the machine is tuned to the pile it is cleaning. Because it is gripped and twisted every time the floor surface changes, it is a small but frequently handled part that can crack, strip, or snap over time.

What the lindhaus adjusting knob does

Mounted on the nozzle’s height mechanism, the Lindhaus Adjusting Knob lets the user dial in the correct brush-to-carpet setting for low-pile, high-pile, or hard-floor cleaning. A knob that grips firmly and clicks between settings keeps the adjustment where you set it. When the knob strips its splines or cracks, the height setting slips or can no longer be changed, and the machine is stuck at one height.

Common signs that the Lindhaus Adjusting Knob needs replacing include a knob that spins freely without changing the height, a cracked or broken knob body, a setting that will not hold, or a missing knob entirely. Fitting a fresh light-grey Lindhaus Adjusting Knob restores proper height control so the brush can be matched to each floor for the best pickup and the least wear.

Replacement is quick and needs only basic hand tools: unplug the vacuum, remove the retaining screw or clip, pull the old knob off the shaft, and press the new part on in the same orientation. Twin City Vacuum has been selling and servicing Lindhaus equipment since 1956, so if you are unsure which knob your machine uses, we can confirm it for you.
